* The debugger then compares values of <BR>
* each thread's suspendCount from first and second Lists. <BR>
* <BR>
* The test has three phases and works as follows. <BR>
* <BR>
* In first phase, <BR>
* upon launching debuggee's VM which will be suspended, <BR>
* a debugger waits for the VMStartEvent within a predefined <BR>
* time interval. If no the VMStartEvent received, the test is FAILED. <BR>
* Upon getting the VMStartEvent, it makes the request for debuggee's <BR>
* ClassPrepareEvent with SUSPEND_EVENT_THREAD, resumes the VM, <BR>
* and waits for the event within the predefined time interval. <BR>
* If no the ClassPrepareEvent received, the test is FAILED. <BR>
* Upon getting the ClassPrepareEvent, <BR>
* the debugger sets up the breakpoint with SUSPEND_EVENT_THREAD <BR>
* within debuggee's special methodForCommunication(). <BR>
* <BR>
* In second phase to check the above, <BR>
* the debugger and the debuggee perform the following loop. <BR>
* - The debugger sets up a StepRequest, resumes <BR>
* the debuggee, and waits for the StepEvent. <BR>
* - The debuggee invokes the special method <BR>
* to be resulting in the event. <BR>
* - Upon getting new event, the debugger <BR>
* performs the check corresponding to the event. <BR>
* <BR>
* Note. To inform each other of needed actions, the debugger and <BR>
* and the debuggee use debuggee's variable "instruction". <BR>
* In third phase, at the end, <BR>
* the debuggee changes the value of the "instruction" <BR>
* to inform the debugger of checks finished, and both end. <BR>
